BESILIENT WHEEL.

Patented June MD, ilt t Application filed July 31, 1 912, Serial-I50. 712.381.

To all whom it may concern:

Be it known that I, AooLrH .ROSEDALE, a citizen of the United States, residing at Alexandria, in the parish of Rapides and 5 State of Louisiana, have invented certain neW and useful Improvements in Resilient -Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable lo-others skilled in the art to which it appertains to make and use the same.

My invention relates to wheel construction and. more particularly to a form of cushion wheel possessing great resiliency and designed to wholly obviate the necessity of using pneumatic tires, and my prime object, among others, is to provide a maximum degree of resiliency and at the same time in no wise decrease in any degree the strength or efficiency of the wheel.

A further special object of my invention is to provide mechanism which will; confine the resiliency to the hub thereby absorbing all blows or jarring incident to passing over uneven surfaces or objects in the roadway.

Other objects and advantages will be hereinafter made clearly apparent, reference being had to the accompanying drawings forming part of this application and in which,

Figure 1 shows a side elevation of my in- -vention completely ready for use. Fig 2 is a sectional view of a wheel showing my invention as applied to use. Fig. 3 is a sectional view of the hub provided with my resilient structure as taken on dotted. line 3-3 of Fig. 2, and Fig. 4 is adetail view showing the special form of socket for re- 40, ceiving one end of one of the plurality of compression springs, through the mediation of which resiliency is secured.

, For convenience in referring to the various elements of my invention and cooperating accessories, numerals will be employed, similar numerals designating corresponding parts throughout the several views.

I desire to call particular attention to the fact that I have confined the resiliency of my wheel to the hub proper and it will be observed by reference to Figs. 1 and 3 that I have rovided a two-part hub, the line of SQPilI'ltlOIl being indicated by the numeral 1, and the hub thus formed is provided with proper of the wheel, I

signed to receive a suitable bore of such diameter as to re ceive the boxing 2 andprovide the annular space 3. surrounding. said boxing. The said annular space is designed: to afi'ond a seat ing for the reception of a plurality of compression springs 4, it being understood that the outer end of each spring is disposed. in a suitable recess 5-, a detailof which is shown in Fig. 4:, formed in the inner surface of the bore of end of each spring is seated a coars sponding recess formed in a contiguous part of the outer surface of the boxing- 2 and it will therefore beobserved that by a proper graduation and mounting 01: the plurality of springs, the said boxing will be held at all times reliably in position, thereby insuring that resiliency oi the springs will be utilized to the fullest extent consistent to the use of the vehicle. By reference toFigs: 2 and 3 it will be observed that the spindle P 'P 6 f he xle- 7 is es gned to fi snugly within the said boxing and it is obvious that the bore of the bQXing may be formed to properly accommodate the tapered outline of the spindle, or a straight bore may be provided if the spindle should be of In Fig. 2 I have shown a tapered bore in the boxing and a tapered spindle, as is common. The hub being formed in two parts permits the ready assembling of the plurality of springs, which are preferably arranged in rows or in alinement with each other, as shown in Figs. 2 and 3, thereby insuring that each spring will carry its proper load at alltimes and by reason of the fact that each end of each spring is seated in a suitable recess it will be impossible for any spring to casually slip out of place. Moreover, in each recess 5, I prefer to form a suitable aperture 8, de-

the extreme end of its re spective spring, whereby the spring will be held against casual rotation.

In order that the members of my twopart hub may be efficiently secured together after the plurality of spring members have been properly mounted in their respective places, it is obvious that any suitable compression means may be employed to force the hub members into close contact with each other,'when a pair of retaining bands 9, one for each end of the hub, may be provided, thereby permanently locking the hub the hub, while the'inner Q noeaaev members together, when the ornamental cap that I have provided a thoroughly reliable, section 10 may be turned home upon a suitdesirable and efiicient form of hub construcable threaded seat and thus insure that dust tion, whereby a great degree of resiliency is will be excluded from the bearings and the insured within the hub proper and the decasual escape of lubricant prevented. In structive blows incident to the use of a ve-' like manner the inner end of the hub may hicle upon a roadway will be wholly abbe provided with a cap member 11, which, sorbed and not communicated to the vehicle when turned home, will in connection with proper or the engine carried thereby, a most the ring member 12 or packing of felt, important and valuable desideratum. leather, or the like, reliably exclude the Believing that the advantages, construcdust, grit, etc. from entering the bearing tion and manner of using my invention seat. The. position of the ring or packing have been set forth, further description is member 12 also insures that a proper dedeemed unnecessary. gree of play of the springs will be possible What I claim as new is:
